Abstract
A suction device has a flexible sucker membrane having a peripherally extending skirt, and an actuator arranged to act to reconfigure the sucker between a suction enhanced configuration and a suction released configuration. The actuator is also operable to lift an outer edge of the peripherally extending skirt which enables more convenient release of the suction device than would otherwise be possible.
Claims20
A suction device comprising:
- a flexible sucker having a peripherally extending skirt;
- an actuator operable to:
- i) apply or release an activating force at a central region of the sucker to reconfigure the sucker between a suction released configuration and a suction enhanced configuration;
- and
- ii) lift an outer edge of the peripherally extending skirt.
A suction device comprising;
- a flexible sucker membrane having a peripherally extending skirt;
- and
- a lever mounted to the sucker membrane, the lever operating an elongate lifter element extending to the peripherally extending skirt, the elongate lifter element operable to lift an edge of the peripherally extending skirt upon operation of the lever.
A suction device including a flexible sucker membrane having a peripherally extending skirt, an underside of the sucker membrane including a suction relieving groove having a relatively wider distal end toward a periphery of the sucker membrane and a relatively narrower proximal end toward a center of the sucker membrane.
